LM15851 的說明
The LM15851 device is a wideband sampling and digital tuning device. Texas Instruments’ giga-sample analog-to-digital converter (ADC) technology enables a large block of frequency spectrum to be sampled directly at RF. An integrated DDC (Digital Down Converter) provides digital filtering and down-conversion. The selected frequency block is made available on a JESD204B serial interface. Data is output as baseband 15-bit complex information for ease of downstream processing. Based on the digital down-converter (DDC) decimation and link output rate settings, this data is output on 1 to 5 lanes of the serial interface.
The LM15851 device is available in a 68-pin VQFN package. The device operates over the Industrial (–40°C ≤ TA ≤ 85°C) ambient temperature range.
